[Elastic osteosynthesis in intracapsular fracture of the femoral neck]

Abstract

The authors present a method of treatment for transcervical fractures of the femoral neck using implants with mechanical characteristics--curved shape, smooth surfaces and elastic resistance to deformity--which respect the biomechanical properties of the normal bone. These implants maintain a close contact between the bony fragments during convalescence and preserve the blood supply of the bone. In this way, bone healing is encouraged and the development of ischaemic necrosis of the femoral head is prevented. Between 1983 and 1985, 126 fractures, of the femoral neck, 120 recent and 6 old, were treated by internal fixation with two short elastic nails. One hundred and seven patients were followed up; fracture healing occurred in 94 cases (87.8 per cent) and 13 developed non-union. There were no necroses of the femoral head.
